I'll start I think a good reliable HP number is between 650-750

I've heard 650 ft/lbs thrown around for the SSM #3. BAM lists the beefed up 3A as rated for 750hp/750tq.
Pros and cons.... Guess those depend on what drive you are comparing them to.

Aren't 3's the ones that are really hard to get parts for?

Planning to push 580 HP on each, so I think it should be ok. Any issues with the Merc transmissions that were used with them?

they are a great upgrade to a bravo xr. you should be just fine with 750 hp. the boat will shift nicely with a trans. and there are still guys out there that can repair them. i believe it will add value to your boat as well. it gives me piece of mind knowing that i have speedmasters on the rear of my boat

Plan your drive height and prop selection ahead of time. At 600hp @ 6000 rpm, and a drive height of. 3" below the bottom, my prop selection was very limited. Needed 16 3/4" diameter min to get on plane, with about 23-24" of pitch. 600 hp was not enough to spin the props. So if your going with 580hp, keep the drives a little low so you can run a more common 16-16.5" prop with 23" pitch.

There are still new internal parts available for the #3 drive. I have new 1.31:1 straight cut, net forged upper gear sets ( the same "gear" as used in the #3A and the #5 drives, but manufactured with the "shank" as I call it, to be used in a #3 drive ) and new 1.75" dia.propshafts available for these drives. These pieces were manufactured in the USA. I can also supply the same upper gear that has a "polygon" internal for the #4 drive.
